Dual-Mode Pushup Exercise Device

ABSTRACT

An exercise device employed to increase the level of difficulty of the standard pushup, while increasing strength, endurance, and flexibility. The device may include a flat, circular plate formed with a dome on one side and a low-friction pad affixed to the other side. The device has two modes of employment and is typically used in a pair, one device gripped in each hand during a pushup exercise. In one mode, the dome side is placed on the floor, forcing the user to stabilize his hands, arms, and upper body over inherently unstable, dome-shaped, high-friction surface during a pushup. The second manner of employment requires the user to stabilize the hands, arms, and upper body over the flat side of the device that has negligible friction against a floor. The devices further have embedded magnets that assist in compact storage when not in use.

RELATED APPLICATION

This application claims the benefit of priority to the U.S. Provisional Patent Application for “Dual-Mode Pushup Exercise Device,” Ser. No. 61/584,458, filed on Jan. 9, 2012, and currently co-pending.

FIELD OF THE INVENTION

The present invention relates generally to fitness and exercise devices. The present invention is more particularly, though not exclusively, a fitness and training aid used to improve the quality of a standard pushup, by concentrating on stabilizer muscles in the upper body.

BACKGROUND OF THE INVENTION

The pushup is a common calisthenics exercise performed in the prone position as illustrated in FIGS. 1 and 2, using the arms to raise and lower the upper body, as the individual “pushes” the floor away, raising the upper body. The pushup, or “press-up” as it has also been known, has been used since the early 1900s as a fitness exercise as well as punishment in schools and in the military. Pushups are an effective upper body exercise that builds muscular strength and endurance in the chest, shoulders, and triceps. The standard pushup is used to exercise the upper body and midsection, including the pectoral muscle group, triceps, and portions of the deltoids, as indicated by the shaded areas in FIG. 3. Other muscles in the upper body and mid-section also receive ancillary benefits from the exercise, depending on the position of the hands and feet during execution of the pushup.

Many fitness tools have been developed in effort to improve the quality of “press” exercises like the pushup. Simple machines such as the “bench press” have been created in order to significantly increase the amount of weight used during the exercise, well in excess of one's own bodyweight, so as to increase strength and endurance. A bench press machine is comprised of a flat, inclined, or declined bench and a weighted bar. The individual lies on the bench and raises and lowers the weighted bar with the same relative motion as the standard pushup, differing only in the fact that the individual lies on his back during the bench press. More complex machines have removed the weighted bar and replaced it with a series of hinges and supports to increase the individual's safety during the exercise, but the exercise remains the same “press.” Most of these exercises, bench press and pushup alike, are limiting in the fact that many of the stabilizing muscles in the forearms, shoulders, and back are ignored during the pushup, because the individual's hands are in a fixed position (either in one place on the floor, or hands gripping the bar) and the linear motion only works the major muscle groups in the exercise, not the smaller stabilizing muscles.

Other implements, such as pushup bars, as shown in FIG. 4, elevate the hands off the floor during a pushup, allowing the upper body to dip below the plane of the hands, and allow the elbows to bend past the 90 degree position during the pushup exercise. Additionally, the elevated position of the hands on the bars also decreases the amount of stress imparted on the wrist during the exercise, because the individual's hands are not flat against the floor, but curled around the pushup bars. This variation increases strength and flexibility, but it too is limited by the fixed position of the hands.

Still another machine, known as “rotating pushup grips” allow the individual to rotate his hands, in a plane parallel to the floor during the pushup exercise. The rotating pushup grips employ ostensibly the same attributes as pushup bars, except they are mounted in such a way so as to allow the bars (or grips) to rotate. Using rotating pushup grips affects the shoulders more than a standard pushup because the hands may rotate, however many of the stabilizing muscles in the arms and shoulders remain ignored, even with the added rotation.

In light of the above, it would be advantageous to provide a pushup exercise device that takes advantage of the benefits of allowing the hands to rotate and move during the exercise.

SUMMARY OF THE INVENTION

The pushup exercise device described herein is used to increase the level of difficulty of a standard pushup and focus more of the users effort on stabilizer muscles in the upper body, specifically the arms and shoulders. The pushup devices are used in pairs and designed to be gripped, one in each hand of the individual executing a pushup exercise. The devices are two-sided, and provide two different methods for the user to increase the difficulty of the pushup exercise. One side of the device is flat and the other side is formed with a hemispherical surface, or dome, such that when the dome is on the ground and the user leans on the flat side, the user must stabilize his or her upper body over the inherently unstable round surface of the dome, using more muscles than an ordinary pushup. The dome side of the device has a high-friction coating to prevent it from supping on the floor. When flipped over, with the flat side of the device on the ground, the user grips the hemispherical, dome-shaped surface. The flat side is fitted with a pad having minimal friction when in contact with a hard surface, allowing the user to slide the devices on a hard surface during an exercise.

The invention is further fit with a magnet, embedded within the flat side of the device, concealed beneath the low-friction pad. The magnet is intended to allow two of the pushup exercise devices to be magnetically coupled for easy storage.

DETAILED DESCRIPTION

The present invention incorporates the mechanics of the standard pushup exercise and elevation of the hands off the floor, while allowing increased freedom of movement of the hands during the pushup exercise. The increase in freedom of movement increases the level of difficulty of the exercise and forces the individual to stabilize the upper body with more muscles than ordinarily required by a standard pushup or with other pushup or “press” exercise machines.

Referring to FIG. 5, the pushup exercise device is generally labeled 100. An embodiment of the invention includes a circular plate 102, formed with a hemispherical dome 104 on one side, generally referred to as the “dome side.” The side opposite the dome 104 will be generally referred to as the “flat side,” and is formed with a low-friction pad 110 affixed to it. FIG. 6 depicts an alternate perspective of device 100, showing the low-friction pad 110, and position of the embedded magnet 114 (shown in dashed lines), beneath the low-friction pad 110.

In a preferred embodiment of the invention, plate diameter 106 is the diameter of the circular plate 102. Accordingly, dome diameter 112, is a measurement of the diameter of the dome 104. Plate diameter 106 may be sized to accommodate the size of the expected user's palm, or any other practical size. As shown in FIGS. 5 and 8, dome diameter 112 is roughly half that of the plate diameter 106, however it is to be appreciated by one skilled in the art, that dome diameter 112 may be varied in size from a diameter smaller than depicted up to and including the plate diameter 106.

An embodiment of the invention has plate diameter 106 sized such that when the palm of the user's hand is placed in the middle of the flat side of the device 100, opposite dome 104, the fingers of that hand may curl over and grip the edge of the device 100. With the hand placed on the flat side, the individual assumes a standard pushup position, as depicted in FIGS. 1 and 2, one device in each hand, with the dame 104 on the floor, and the individual's fingers curled over the edge of the devices 100. The hemispherical shape of the dome 104 creates an unstable platform upon which the user leans during a pushup, as depicted in FIG. 10. Because the hands, and pushup devices 100 may rock or rotate about the curved surface of dome 104, the device is inherently unstable and increases the level of difficulty, forcing the user to use stabilizing muscles ignored by the ordinary pushup exercise.

An embodiment of the invention varies the dome diameter 112 to increase or decrease the instability of the devices, thereby affecting demand on the muscle response required to remain stable while in use.

In a preferred embodiment the hands are elevated off the floor allowing a greater range of motion in the pushup, which allows for a greater range of motion in the exercise. Additionally, because the user's fingers are curled over the edge of the fiat side of the circular plate 102, this mode of operation also decreases the amount of strain directed at the wrist of the individual using the described pushup exercise devices.

Referring to FIG. 6, an embodiment of the invention has a nylon, delrin, neoprene, or similarly coated low-friction pad 110 on the flat side of the device 100. In this embodiment, the user places the flat side, or low-friction pad 110 of the invention on the ground, and places the palm of his or her hand on the dome 104, as depicted in FIG. 11. The user then may take the standard pushup position, as in FIGS. 1 and 2, again with one device in each hand. When used on a hard surface, such as a linoleum, tile, or hardwood floor, friction between the low-friction pad 110 and the floor is slight. In this mode, the user may execute the pushup exercise with the freedom of movement to slide the devices on the floor. This embodiment incorporates not only the pushup itself, but also forces the individual to again stabilize the device 100 under him or her during exercise in order to keep the device 100 from sliding out from under the upper body. The less friction that is created between the low-friction pad 110 and the floor, the more difficult the pushup exercise becomes. Alternatively, the user may choose to slide the devices on the hard surface and vary the exercise to include various hand positions or an abdominal exercise.

A preferred embodiment of the invention further includes a magnet 114 embedded within the circular plate 102, concealed beneath the low-friction pad 110, as shown in FIGS. 6, 7, and 9, in dashed lines. This allows two devices 100 to magnetically attach to each other for more compact storage.

An embodiment of the invention incorporates an exterior coating with a high friction material, such as a rubber, vulcanized, or otherwise nonskid coating, that prevents the dome 104 from sliding if used on a hard or slippery surface. This nonskid characteristic of the surface of the dome 104 also provides a more effective gripping surface for the user when used with the flat side in contact with the floor.

Referring to FIG. 12, an alternative embodiment of the invention is shown and generally referred to as device 200. Device 200 varies the shape of the plate 102 that forms the flat side of the device 100 as shown in previous FIGS. 5-10. The shape of plate 202 and low-friction pad 210 in FIG. 12 are not round as in previous embodiments, and are replaced with a non-circular or ergonomic shape. The different shape retains the same characteristics as a previous embodiments, allowing the device to be employed both dome 204 side down and flat side down with the low-friction pad 210 in contact with the floor. This shape allows the user to more effectively grip the device 200 during exercise. Further, the shape of the plate 202 and low-friction pad 210 may be varied to compensate for users with different sized hands. Additionally, in this embodiment, the individual devices may be formed as mirror images of one another, allowing one for the left and right hands.
